Dear,

Contact to the college of RVCE. and don't tell that you want to join another college. Try to take out your documents and fees. Give some strong reason so that college authority can understand your  lie reason. like medical reason but with the medical certificeted so that they can trust you.

Make sure the reason will be strong. It it happen then college will refund you with the doucments.

I hope you catch my point.

ALL THE BEST.
